FIELD OF THE INVENTION

The present disclosure relates to: a) methods of synthesizing N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide; b) crystalline forms of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide; c) pharmaceutical compositions comprising one or more crystalline forms of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide, and, optionally, one or more pharmaceutically acceptable carriers; and d) methods of treating a tumor, a cancer, or a Rasopathy disorder by administering one or more crystalline forms of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide to a subject in need thereof.

BACKGROUND

N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide (“mirdametinib”, or “PD-0325901”) is a small molecule drug which has been designed to inhibit mitogen-activated protein kinase kinase 1 (“MEK1”) and mitogen-activated protein kinase kinase 2 (“MEK2”). MEK1 and MEK2 are proteins that play key roles in the mitogen-activated protein kinase (“MAPK”) signaling pathway. The MAPK pathway is critical for cell survival and proliferation, and overactivation of this pathway, has been shown to lead to tumor development and growth. Mirdametinib is a highly potent and specific allosteric non-ATP-competitive inhibitor of MEK1 and MEK2. By virtue of its mechanism of action, mirdametinib leads to significantly inhibited phosphorylation of the extracellular regulated MAP kinases ERK1 and ERK2, thereby leading to impaired growth of tumor cells both in vitro and in vivo. In addition, evidence indicates that inflammatory cytokine-induced increases in MEK/ERK activity contribute to the inflammation, pain, and tissue destruction associated with rheumatoid arthritis and other inflammatory diseases.

Crystal forms of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide have been described previously. WO2002/006213 describes crystalline Forms I and II. U.S. Pat. No. 7,060,856 (“the '856 patent”) describes a method of producing Form IV. The '856 patent indicates that the material produced by this method was greater than 90% Form IV (The '856 patent, Example 1). The '856 patent also states that the differential scanning calorimetry (“DSC”) of the material produced shows an onset of melting at 110° C. as well as a small peak with an onset at 117° C., consistent with the material being a mixture of two forms.

WO 2006/134469 (“the '469 PCT publication”) also describes a method of synthesizing N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide. The '469 PCT publication reports the method yields a product conforming to the polymorphic Form IV disclosed in U.S. patent application Ser. No. 10/969,681 which issued as the '856 patent.

Differences in the characteristics of different polymorphic forms can lead to differences in the effective dose or physical properties affecting processability of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide caused by differences in solubility or bioavailability. Thus, there is a need for compositions of polymorphic forms of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide, for use in treatment of a tumor, a cancer, or a Rasopathy disorder.

The term “pharmaceutical composition,” as used herein, represents a composition containing a compound described herein formulated with one or more pharmaceutically acceptable excipients (carriers), and can be manufactured or sold with the approval of a governmental regulatory agency as part of a therapeutic regimen for the treatment of disease in a mammal. Pharmaceutical compositions can be formulated, for example, for oral administration in unit dosage form (e.g., a tablet (e.g., dispersible tablet), powder (e.g., dispersible powder) capsule, granules, minitablets, pellets, caplet, gelcap, or syrup).

The terms “about” or “approximately” means within a range of an acceptable error for a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined. In some aspects, the term “about” or “approximately” means within 1, 2, 3, or 4 standard deviations. In some aspects, the term “about” or “approximately” means a quantity, level, value, number, frequency, percentage, dimension, size, amount, weight or length that varies by as much as 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1% to a reference quantity, level, value, number, frequency, percentage, dimension, size, amount, weight or length.

As used herein, the term “administration” refers to the administration of a composition (e.g., a compound or a preparation that includes a compound as described herein) to a subject or system. Administration to an animal subject (e.g., to a human) can be by any appropriate route, such as one described herein.

The term “solvate” refers to a compound provided herein or a salt thereof, which further includes a stoichiometric or non-stoichiometric amount of solvent bound by non-covalent intermolecular forces. Where the solvent is water, the solvate is a hydrate. Where the solvent includes ethanol, the compound can be an ethanol solvate.

The term “crystalline,” as used herein, refers to a solid-state form which consists of orderly arrangement of structural units. Different crystalline forms of the same compound, or a salt, hydrate, or solvate thereof, arise from different packing of the molecules in the solid-state, which results in different crystal symmetries and/or unit cell parameter. Different crystalline forms usually have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. See, e.g., Remington's Pharmaceutical Sciences, 18^(th) ed., Mack Publishing, Easton Pa., 173 (1990); The United States Pharmacopeia, 23^(rd) ed., 1843-1844 (1995) (incorporated herein by reference).

Crystalline forms are commonly characterized by X-ray powder diffraction (XRPD). An XRPD pattern of reflections (peaks, typically expressed in degrees 2-theta) is commonly considered a fingerprint of a particular crystalline form. The relative intensities of the XRPD peaks can widely vary depending on, inter alia, the sample preparation technique, crystal size distribution, filters, the sample mounting procedure, and the particular instrument employed. In some instances, new peaks may be observed or existing peaks may disappear, depending on the type of instrument or the settings. In some instances, any particular peak in an XRPD pattern may appear as a singlet, doublet, triplet, quartet, or multiplet, depending on the type of instrument or the settings, the sensitivity of the instrument, measuring conditions, and/or purity of the crystalline form. In some instances, any particular peak in an XRPD may appear in a symmetric shape or in an asymmetric shape, e.g., having a shoulder. Moreover, instrument variation and other factors can affect the 2-theta values. A skilled artisan understanding these variations is capable of discriminating or ascertaining the defining features or characteristics of a particular crystal form using XRPD, as well as using other known physicochemical techniques.

The term “anhydrate” as applied to a compound refers to a crystalline form wherein the compound contains no structural water within the crystal lattice.

As used herein, the term “essentially pure” with respect to Form IV means that the composition comprising Form IV contains no detectable amount of another polymorphic form (e.g., Form I or Form II), as determined by observing no detectable differences in an XRPD and/or DSC pattern between a single Form IV crystal and the crystalline composition of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide. However, “essentially pure” Form IV of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide can include impurities, such as, but not limited to, synthetic reactants or by-products generated during the chemical synthesis.

As used herein, the term “aberration” as applied to a gene refers to a mutation, chromosomal loss or fusion, epigenetic chemical modification, or other event which alters the sequence, level of expression, or processed mRNA sequence associated with a gene relative to the sequence, level of expression, or processed mRNA sequence associated with the wild-type gene.

It is understood that wherever aspects are described herein with the language “comprising,” otherwise analogous aspects described in terms of “consisting of” and/or “consisting essentially of” are also provided.

The details of one or more aspects are set forth in the description below. Other features, objects, and advantages will be apparent from the description and from the claims.

The triflate activation was performed in the 200 L reactor by maintaining temperatures under −20° C. during triflic anhydride addition. The resulting activated alcohol was then transferred to a 400 L reactor containing solid N-hydroxypthalimide (NHP) and the reaction was allowed to occur at ambient temperature to completion. The final base de-protection was performed by adding aqueous ammonia (˜28% soln, 5 equiv., 34 kg). After reaction completion, water was removed by distillation from toluene, and the resulting solid side product was filtered out to yield the product solution.

Step 2: Preparation of PD-0315209

The process yielded 21.4 kg (99.4% w/w assay), which is 80% of theoretical from starting materials 2,3,4-trifluorobenzoic acid (12 kg, 1 eq.) and 2-fluoro-4-iodoaniline (16.4 kg, 1.02 eq.) with lithium amide base (5 kg, 3.2 eq.). The reaction was initiated by adding 5% of total solution of TFBA and FIA into lithium amide slurry at 50° C. This reaction demonstrated a minimal initiation period of ˜10 minutes, which was observed by color change and slight exotherm. The remaining TFBA/FIA solution in THF was slowly added through a pressure can in an hour while maintaining the reaction temperatures within 45-55° C. There was no appreciable pressure rise (due to ammonia gas release) observed during the entire operation.

Step 3: Preparation of PD-0325901

A modification was made to the CDI charging to mitigate potential gas generation. Two equal portions of CDI were added into solid FIPFA before and after solvent addition (through a shot loader). The timing between the two solid CDI additions (4.6 kg each) should not exceed 30 minutes. Then two intermediate filter cakes were dissolved with ethanol. The excess ethanol was distilled and replaced with toluene to approximately 5% v/v ethanol prior to PD-0325901 recrystallization. Lab studies suggested that the crystallization from toluene and acetonitrile and recrystallization from ethanol in toluene would not be able to reduce impurities which is essential for the polymorph transformation. The presence of a dimeric impurity (PF-00191189) at a level greater than 0.2% has been known to result in the formation of undesired polymorph.

The crude crystallization from the final reaction mixture reduced dimeric impurity PF-00191189 to approximately 1.9/6 and the subsequent recrystallization further reduced it to approximately 0.4%. As a consequence, undesired polymorphs were produced. The DSC patterns indicated two different melting points ˜80° C. (low melt Form II) and ˜117° C. (Form I). Also during the processing, the solids crystallized at a much lower temperature than expected (actual ˜10° C., expected ˜40° C.). It is suspected that the unsuccessful recrystallization is due to a change in the solvent composition as a result of incomplete drying of the crude. Drying of the crude wet cake prior to ethanol dissolution was stopped after about 36 hours when the crude product was ˜28 kg (26 kg theoretical).

Polymorph Transformation

Approximately 7.4 kg of PD-0325901 (mixed polymorphs) from the final EtOH/Water crystallization and precipitated materials from the earlier EtOH/Toluene filtrate were taken forward to the polymorph transformation. Both crops were separately dried in the filter until constant weights and each was dissolved in EtOH. The combined EtOH solution was analyzed by HPLC and resulted in an estimated amount of 16.4 kg PD-0325901. The recrystallization was started after removing EtOH via vacuum distillation and adjusting the solvent composition to about 5% EtOH in Toluene at 65° C. (i.e., EtOH is added dropwise at 65° C. until complete solids dissolution).

A slow 4-hour cooling ramp to 5° C. followed by 12 h stirring was performed to ensure satisfactory results. The resulting slurry was filtered and again it was completely dried in the filter until constant weight (approximately 3 days). The purified solid showed 99.8% pure PD-0325901 with not detected level of dimeric impurity PF-00191189.

The dried solid (15.4 kg) was re-dissolved in exactly 4 volumes of EtOH (62 L) off of the filter, transferred to the reactor and precipitated by a slow (˜3 h) water addition (308 L) at 30-35° C., cooled to 20° C. and stirred for 12 h. The DSC analysis of a slurry sample taken at 2 h shows the solids to be completely Form IV (desired polymorph).

21.4 kg PD-0315209, 9.7 kg CDI (1.05 equiv.), 91 kg solution of 9.7% PD-0337792 in Toluene (1.1 equiv.) were used and resulted in 12.74 kg of PD-0325901 (assay 99.4%, 100% Form IV, Yield ˜48%).

Example 2: Assay/Impurities and Identification of PD-0325901

PD-0325901 is separated from process impurities and degradants by reversed-phase liquid chromatography with UV detection at 275 nm. Identification of PD-0325901 is performed by obtaining either an infrared or proton NMR spectrum, in addition to the HPLC retention time. For purity evaluation, process impurities and degradants are identified by their characteristic relative retention times and quantitated by area normalization.

Chromatographic Conditions: Agilent Zorbax SB C18, 5 μm, 4.6×250 mm (or equivalent); flow rate is 1.0 mL/min; column temperature is 30° C.; detector wavelength is 275 nm; diluent is 50/50 acetonitrile/water; mobile phase A is 0.1% trifluoroacetic acid (TFA) in water; mobile phase B is methanol; and the gradient conditions below.

Example 3: Improved Process for Preparation of Form IV

As described in Example 1, synthetic methods of producing mirdametinib as Form IV produced Form IV with dimeric impurity PF-00191189, and further steps were required to transform the product into essentially pure Form IV without undesired polymorphs Form I and Form II. Therefore, it was necessary to develop a method of producing essentially pure Form IV without additional processing steps.

Mirdametinib Manufacturing Process

The route is a convergent four step synthesis with six chemical steps overall, using the proposed starting materials (S)-(+)-2,2-dimethyl-1,3-dioxolane-4-methanol (SGA), 2,3,4-trifluorobenzoic acid (TFBA), 2-fluoro-4-idodoaniline (FIA), and N-hydroxyphthalimide (NHP). The final step (Step 4) provides essentially pure Form IV of mirdametinib.

Step 1 (Preparation of PD-0337792 (IPGA)): A clean, dry 100-gallon reactor was charged with toluene (139.3 kg, 8 volumes) and (S)-(+)-2,2-Dimethyl-1,3-dioxolane-4-methanol (SGA; 20.0 kg, 1.0 equivalents). Triethylamine (18.8 kg, 1.22 equivalents) was charged to the reactor. The reactor contents were agitated and cooled to −10±10° C. Trifluoromethanesulfonic anhydride (43.5 kg, 1.02 equivalents) was added to a clean 50-L round bottom flask under nitrogen then cooled to a temperature of ≤−10° C. The cooled trifluoromethanesulfonic anhydride was slowly transferred to the 100-gallon reactor while maintaining the internal temperature at −10±10° C. The reaction mixture was agitated at −10±10° C. for 30 minutes. Reaction monitoring by TLC indicated the conversion to be complete. While maintaining the internal temperature at −10±10° C., anhydrous toluene (99.8 kg, 5.75 volumes) was charged to the reactor followed by N-hydroxyphthalimide (26.4 kg, 1.07 equivalents). The contents were warmed to 20±5° C. then agitated at this temperature for at least 5 hours, until the triflate intermediate was not detectable by TLC. The reaction mixture was split into two equal portions. Each toluene solution was quenched with USP purified water (66 kg, 6.7 volumes). The toluene solution was then washed twice with USP purified water (66 kg, 6.7 volumes).

The toluene solutions were recombined in a 100-gallon reactor. The organic solution was treated with 28% ammonium hydroxide solution (41.5 kg, 7.8 equivalents). The contents were heated to 35±5° C. then agitated for not less than (“NLT”) 12 hours. Upon reaction completion, the lower, aqueous phase was removed. The toluene solution was dried via azeotropic distillation of toluene. The toluene solution was then concentrated to minimum stir volume. The concentrated solution was filtered to remove by-product solids. The cake was washed with toluene and the filtrates were combined. Assay of the toluene solution indicated 8.6 kg (36.7% yield) of PD-0337792 (IPGA) was present.

Step 2 (Preparation of PD-0315209): A clean, dry 100-gallon reactor was purged with nitrogen then charged with lithium amide (LiNH2, 8.8 kg, 3.4 equivalents) followed by tetrahydrofuran (THF, 56.8 kg, 3.2 volumes). The mixture was cooled to 10±10° C. then additional THF (15.1 kg, 0.85 volumes) was charged to the reactor, followed by a solution of 2,3,4-trifluorobenzoic acid (TFBA, 20.0 kg, 1.0 equivalent) in THF (26.4 kg, 1.15 volumes). The reaction mixture was heated to NMT (“not more than”) 50° C. A solution of 2-fluoro-4-iodoaniline (FIA, 27.5 kg, 1.02 equivalents) in THF (17.8 kg, 1 volumes) was added portion wise to the reactor, maintaining the batch temperature at NMT 50° C. and stirring for 1 hour between additions. After completing the additions, the reaction mixture stirred for an additional 3 hours at 50±10° C. Upon reaction completion, the mixture was cooled to NMT 10° C. then quenched with USP purified water (120.3 kg, 6 volumes). The reaction mixture was distilled to approximately 30 gallons after which methyl t-butyl ether (MTBE, 118.6 kg, 8 volumes) was added. The MTBE solution was then quenched with 2M hydrochloric acid solution (89.5 kg) to a pH=7. The aqueous phase was then removed. The MTBE solution was filtered through celite then washed twice with 5% brine solution (104.1 kg, 5.2 volumes) followed by 1M hydrochloric acid solution (77.4 kg). The MTBE solution was solvent swapped with toluene followed by volume adjustment to approximately 50 gallons. This mixture was heated to 75±5° C. for 1 hour then cooled to 20±5° C. and stirred for 1 hour. The product was filtered, washed with toluene (68.1 kg, ˜4 volumes), then dried under vacuum at 40° C. to obtain 25.2 kg of PD-0315209 (56.4% yield).

Step 3 (Preparation of crude PD-0325901): A clean, dry 100-gallon reactor was purged with nitrogen then charged with PD-0315209 (18.0 kg, 1 equivalent) and THF (113.0 kg, 7 volumes). The mixture was cooled to 5±5° C. N,N-diisopropylethylamine (15.1 kg, 2.55 equivalents) was charged maintaining the temperature NMT 25° C. The mixture was cooled to 5±5° C. then stirred for 10 minutes. PD-0337792 solution in toluene (121.7 kg total, 1.3 equivalents) was charged to the reactor at 5±5° C., followed by 50% T3P in ethyl acetate (42.0 kg, 1.45 equivalents). The reaction mixture stirred at 10±5° C. for NLT 3 hours. An additional charge of N,N-diisopropylethylamine (1.9 kg, 0.3 equivalents) and 50% T3P in ethyl acetate (4.1 kg, 0.15 equivalents) were made to advance the coupling to completion. The reaction was reverse quenched into a 5% sodium hydroxide solution (50 kg), followed by washing with 5% brine (55.4 kg). The organic solution was concentrated then solvent swapped with toluene. Acetonitrile (43.0 kg, 2.4 volumes) was added to the reactor followed by 2M hydrochloric acid (117.6 kg, 5.1 equivalents). The mixture stirred at 25±5° C. until reaction completion after 16 hours. The bottom aqueous was removed then the reaction mixture was washed with 5% brine (75.2 kg). The organic phase was concentrated then solvent swapped with toluene to an appropriate volume. The mixture was then heated to 75±5° C. for 30 minutes then slowly cooled to 20° C. The solids were filtered then washed with toluene (31.1 kg, 1.7 volumes)

The crude solids were charged back to the 100-gallon reactor, followed by 5% ethanol in toluene (170.0 kg). The mixture was heated to 75±5° C. for 60 minutes to achieve a solution then slowly cooled to 20° C. The solids were filtered then washed twice with toluene (31 kg, 1.7 volumes). The wet cake was dried under vacuum at 45° C. to obtain 8.2 kg of crude PD-0325901 (37.1% yield).

Step 4 (Preparation of Essentially Pure Form IV Mirdametinib): A clean, dry 100-gallon reactor was purged with nitrogen then charged with USP Purified Water (164.1 kg, 20 volumes) followed by ethanol (200 proof, 20.8 kg, 3.25 volumes). The solution was heated to 35±5° C. In a separate vessel, crude PD-0325901 (8.1 kg, 1 equivalent) was dissolved in ethanol (200 proof, 40.5 kg, 6.3 volumes). A portion of this solution (14.4 kg) was added to the 100-gallon reactor over 60 minutes. PD-0325901 Form IV seeds as prepared in Example 1 (82.6 g, 1% wt) was added to the reactor to facilitate precipitation. The remainder of the crude PD-0325901/ethanol solution (34.3 kg) was added to the reactor over 90 minutes as the mixture stirred at 35±5° C. The reactor contents continued to stir at 35±5° C. for 5.5 hours then were slowly cooled to 20° C. The solids were then filtered, washed with USP purified water (16.5 kg, 2 volumes), then dried under vacuum at 45° C. for 16 hours. The dried solids were screened through a 10-mesh sieve to obtain 5.7 kg PD-0325901 Form IV (70.4% yield).

An XRPD pattern for essentially pure Form IV used herein is shown in FIG. 1A. TGA and DSC analysis of essentially pure Form IV used herein are shown in FIG. 1B.

Example 4: Approximate Kinetic Solubility

Solubility of mirdametinib prepared by Example 3 was assessed in 30 solvents. The solubility was visually estimated at room temperature (RT; ˜23° C.) by dosing small aliquots of solvent into a fixed amount of solid (˜10 mg) until the dissolution point or a maximum volume (1.8 mL) was reached. Samples that contained undissolved solids at RT were heated to 40° C. for 1 hour and the dissolution was assessed visually. The solubility data are shown below in Table 1.

Example 5: Comprehensive Crystal-Form Screening

About 450 crystallization experiments were performed using the mirdametinib prepared in Example 3 to identify novel polymorphs and solvates/hydrates of mirdametinib. The description of crystallization methods and solid-state forms of the input materials are described here.

Crystallization Modes

Four main types of crystallization modes were employed in the screening study:

Slurry Equilibration:

-   -   Isothermal at 5, 25, and 50° C. for 48-72 hours     -   Thermocycling between 40-5° C. (in one-hour periods) for 48         hours

Rapid and Controlled Cooling of Clarified Solutions of Mirdametinib:

-   -   Controlled cooling from 50° C. to 5° C. at a rate of 0.1° C./min         with one hour hold every 5° C. followed by hold at 5° C. for 5         days, followed by hold at −20° C. (for remaining solutions) for         6 to 9 days     -   Rapid cooling from 50° C. to −20° C. at an uncontrolled rate         followed by hold at −20° C. for 4 to 14 days

Rapid and Slow Evaporation of Clarified Solutions of Mirdametinib:

-   -   Slow evaporation over up to 30 days at ambient conditions     -   Rapid evaporation for up to 3 days at reduced pressure at         ambient temperature

Addition of Antisolvent to Saturated and Clarified Mirdametinib Solutions at Room Temperature:

-   -   Rapid antisolvent addition and stirring at ambient temperature         for up to 11 days

Example 6: Amorphous Material Preparation and Experiments

Amorphous mirdametinib was prepared on a 100 mg scale by rapid evaporation under reduced pressure (Genevac® vacuum centrifuge) of 100 mg/mL solutions of the mirdametinib in methanol and THF (A-1 and A-2, respectfully).

Solutions of mirdametinib (100 mg/mL) were prepared in methanol and THF, and each solution was divided into three equal parts to be used for 1) open at RT stability evaluation, 2) closed at RT stability evaluation, and 3) closed at −20° C. stability evaluation. Observations after rapid evaporation revealed that the samples from methanol were mostly dry, glassy materials, and the samples from THF were mostly sticky, dark amber gums.

PXRD analyses of all six samples (three from both methanol and THF) following rapid evaporation indicated an amorphous state. Other analyses (e.g. PLM, TGA-IR, DSC) were performed on one sample from each solvent. Following initial analyses, one sample from each solvent was stored at RT in an open vial, at RT in a capped vial, and at −20° C. in a capped vial.

PXRD and PLM analyses after one day showed no crystallization in A-1a (open at RT), and A-1b (capped at RT) from methanol. A-1c (capped at −20° C.) was not analyzed.

PXRD and PLM analyses after one day showed crystallization to Form IV in A-2a (open at RT) from THF. A-2b (capped at RT) and A-2c (capped at −20° C.) were not analyzed.

Since amorphous mirdametinib (A-1) was successfully prepared at 100 mg scale by rapid evaporation at reduced pressure from a methanol solution, this method was used to prepare vials containing amorphous material for use as the input material for slurry-ripening experiments in the screen.

Amorphous Mirdametinib Experiments

Experiment Procedure Results A-1 A-1: Combined 299.8 ms of mirdametinib with 3 mL of Amorphous methanol and stirred for 1 hour yielding a solution. Filtered the (after 1 day at solution through 2 μm PTFE filter to clarify. ambient) Pipetted 900 μL of A-1 above into 3 separate 2 mL vials: A-1a, A-1b, and A-1c. Rapidly evaporated the solvent under reduced pressure in a vacuum centrifuge (GeneVac ®) for 20 hours. Products were mostly glassy with a thin film of dark amber on bottom. PXRD and PLM analyses of all 3 samples indicated they were initially amorphous. Analyzed A-1a by PLM, TGA-IR, and DSC. DSC data was consistent with an amorphous state. TGA-IR showed 1.3% wt. water and MeOH evolved upon heating to 200° C. PXRD and PLM analyses of A-1a, after one day open at RT indicated an amorphous state. A- 2 A-2: Combined 298.9 mg of mirdametinib with 3 mL of THF Form IV and stirred for 1 hour yielding a solution. Filtered the solution (after 1 day at through 2 μm PTFE filter to clarify. ambient) Pipetted 900 μL of A-2 above into 3 separate 2 mL vials: A-2a, A-2b, and A-2c. Rapidly evaporated the solvent under reduced pressure in a vacuum centrifuge (Gene Vac ®) for 20 hours. Product was a dark amber clear gum with some glassy material on top. PXRD and PLM analyses of all three samples indicated they were initially amorphous. Analyzed A-2a by PLM and TGA-IR. TGA-IR showed 7.8% wt water and THF evolved upon heating to 200° C.. PXRD and PLM analyses of A-2a after one day open at RT showed crystallization to the supplied Form IV.

Characterization of Amorphous Material (A-1)

PXRD and PLM analyses indicated the material was non-crystalline. DSC analysis showed no melting endotherm up to 200° C., which is consistent with an amorphous phase. TGA-IR analysis showed about 1.3% wt. loss of water and methanol upon heating from 26-200° C. Amorphous mirdametinib was physically stable in both open and closed vials for at least 24 hours at RT.

Example 7: Results of Crystal-Form Screen

The crystal-form screen consisted of about 450 crystallization experiments covering crystalline and amorphous input materials, and various crystallization modes, solvents, and temperatures.

Four hydrates (designated Forms VI, XIII, XIX and XX) were observed and appear to be novel forms. Water activity experiments conducted between non-solvated Form IV and two stable hydrates (Forms VI and XIX) indicated that Form IV is more stable at water activities (aw) 0.6-0.99 than hydrate Forms VI and XIX.

Fifteen solvates (designated Forms V, VII-XII, XV-XVIII, and XXI-XXIV) observed included process-related toluene (Form V), toluene/MIBK (Form VIII), and unstable toluene (Form IX) solvates.

Mirdametinib/process solvent conversion studies involving stirring the toluene solvate (Form V) in 1.1/0.5 (v/v) water/ethanol at RT with varying amounts of added toluene indicated that if crude mirdametinib from toluene/ethanol was the pure toluene solvate, controlling toluene levels going into the final crystallization could be critical. However, if the crude API is mostly Form IV with lesser amounts of the toluene solvate, it may not be as critical to monitor toluene levels in the crude mirdametinib.

PXRD and PLM analysis indicates that the material is crystalline. DSC analysis shows a single sharp endotherm with onset at about 111° C. (ΔH=85.6 J/g). TGA-IR analysis shows about 0.15% wt. loss to 150° C., indicating a non-solvated form. Form XIV was found to convert to Form IV within four days at ambient conditions. Form XIV was not scaled up to be used for further studies (e.g. relative stability studies).

Toluene Solvate Form V

The characterization data for Form V, a process-relevant toluene solvate, are presented in FIG. 3A and FIG. 3B. PXRD and PLM analysis indicates that the material is crystalline. DSC analysis shows two overlapping endotherms with onsets at about 77° C. (ΔH=44.3 J/g) and about 95° C. (ΔH=33.2 J/g). TGA-IR analysis shows about 2.7% wt. (0.15 eq) loss of toluene upon heating to 100° C. and about 4.7% wt. (0.26 eq) total loss of toluene upon heating to 185° C., indicating a solvated form. Form V was found to be stable at ambient conditions for ≥10 days. Form V was scaled up to be used for focused studies around the mirdametinib crystallization process.

Preparation of Form V

Mirdametinib (308.0 mg) was dissolved in 3.0 mL of methanol and the solution was filtered through a 0.2 μm PTFE filter. The solution was rapidly evaporated under reduced pressure (GeneVac®) overnight to yield amorphous material. Toluene (150 μL) and a stir disc was added to the amorphous product and the mixture was stirred at 25° C. for 35 min. Seeds (˜1 mg) were added, and the sample was stirred at 25° C. for 23 hours. The damp solids were dried in a nitrogen flow chamber for 3 hours. The batch weight was about 212 mg, and the yield was about 69% wt. of Form V.

Form VII (Toluene/MIBK Solvate)

The characterization data for Form VIII, a toluene/MIBK solvate, are presented FIG. 6A and FIG. 6B. PXRD and PLM analysis indicates that the material is crystalline. DSC analysis shows a broad endotherm with onset at about 81° C. (ΔH=67.1 J/g) followed by a small broad endotherm with onset at about 110° C. (ΔH=7.1 J/g). TGA-IR analysis shows about 3.3% wt. loss of toluene and MIBK upon heating to 112° C. and about 0.8% wt. additional loss of toluene and MIBK upon heating from 112 to 150° C., indicating a solvated form. Form VIII was stable at ambient conditions for ≥2 days. Form VIII was not scaled up for further studies (e.g., focused studies around the mirdametinib crystallization process).

Unstable Toluene Solvate Form IX

The characterization data for Form IX, an unstable toluene solvate, are presented in FIG. 7A and FIG. 7B. PXRD and PLM analysis indicates that the material is crystalline. DSC analysis shows a broad endotherm with onset at about 84° C. (ΔH=17.1 J/g), an endotherm at about 107° C. (ΔH=12.4 J/g), and a sharper endotherm with onset at about 114° C. (ΔH=39.6 J/g). TGA-IR analysis shows about 4.6% wt. loss of toluene upon heating to 128° C., indicating a solvated form. Form IX exhibited significant conversion toward Form IV after 20 hours at ambient conditions. Form IX was not scaled up for further studies (e.g. focused studies around the mirdametinib crystallization process).

Hydrate Form VI

The characterization data for Form VI, a hydrate, are presented in FIG. 4A and FIG. 4B. PXRD and PLM analysis indicates that the material is crystalline. DSC analysis shows three broad endotherms with onsets at about 41° C. (ΔH=11.4 J/g), about 70° C. (ΔH=48.1 J/g), and about 109° C. (ΔH=21.3 J/g). TGA-IR analysis shows about 2.4% wt. (0.7 eq) loss of water upon heating to 125° C., indicating a hydrated form. Form VI was found to be stable for ≥2 weeks in solid-state at ambient conditions. Form VI was scaled up to be used for water activity studies between non-solvated Form IV and the stable hydrates.

Preparation of Form VI/Form IV Mixture

Mirdametinib (120.8 mg) was dissolved in 1.0 mL of methanol. The solution was filtered through a 0.2 μm PTFE filter and rapidly evaporated under reduced pressure (GeneVac®) overnight. Water (1.0 mL) and a stir disc were added to the dry solids, followed by seeds (˜0.1 mg). The suspension was mixed at 25° C. for 24 hours, and the solids were isolated by vacuum-filtration. The batch weight was about 58 mg, and the yield was an about 48% wt. of a mixture of Form VI and Form IV.

Hydrate Form IX

The characterization data for Form IX, a hydrate, are presented in FIG. 7A and FIG. 7B. PXRD and PLM analysis indicates that the material is crystalline and contains some Form IV. DSC analysis shows two broad endotherms with onsets at about 55° C. (ΔH=66.8 J/g) and about 109° C. (ΔH=25.5 J/g). TGA-IR analysis shows about 3.1% wt. (0.9 eq) loss of water upon heating to 100° C., indicating a hydrated form. Form IX was observed only once (as phase-pure) during screening, and it was observed to slowly convert to Form IV in solid-state at ambient conditions. Form IX was not scaled up for further studies (e.g., water activity studies).

Hydrate Form XIX

The characterization data for Form XIX, a hydrate, are presented in FIG. 17A and FIG. 17B. PXRD and PLM analysis indicates that the material is crystalline. DSC analysis shows a broad endotherm with onset at about 69° C. (ΔH=28.5 J/g), followed by an exotherm with onset at about 98° C. (ΔH=13.5 J/g), and a sharp endotherm with onset at about 115° C. (ΔH=59.6 J/g). TGA-IR analysis shows about 1.85% wt. (0.5 eq) loss of water upon heating to 92° C., indicating a hydrated form. Form XIX was found to be stable in a capped vial for ≥2 weeks. Form XIX was scaled up to be used for water activity studies between non-solvated Form IV and the stable hydrates.

Preparation of Form XIX

Mirdametinib (about 497 mg) was dissolved in 3.0 mL of water:MeOH (40:60 v/v) by mixing at 50° C. for 10 min. The solution was filtered hot through a 0.2 μm PTFE filter into a second vial at 50° C. The solution was rapidly cooled to −20° C., and seeds (1-2 mg) were added and dispersed by swirling. After 30 min., the product was a thick paste, so 1.0 mL more solvent was added, and the suspension cooled at −20° C. for 30 min. The solids in the cold suspension were isolated by vacuum-filtration, then allowed to air dry for 16 hours. The batch weight was about 278 mg, and the yield was about 56% wt. of Form XIX.

Hydrate Form XX

The characterization data for Form XX, a hydrate, are presented in FIG. 18A and FIG. 18B. PXRD and PLM analysis indicates that the material is crystalline. DSC analysis shows three broad endotherms with onsets at about 77° C. (ΔH=29.0 J/g), about 92° C. (ΔH=9.8 J/g) and about 110° C. (ΔH=6.8 J/g). TGA-IR analysis shows about 2.6% wt. (0.7 eq) loss of mostly water with a small amount of acetonitrile upon heating to 126° C., indicating a hydrated form. TGA-IR analysis of a second less-crystalline sample of Form XX showed only water evolved upon heating. Form XX was found to convert to Form IV within 10 days at ambient conditions. Form XX was not scaled up for further studies (e.g., water activity studies).

Example 9: Water Activity Studies of Hydrates at 23° C.

Water activity studies of the stable hydrated Forms VI and XIX were conducted to determine their relative thermodynamic stabilities. The studies were conducted at 23° C. in various water/ethanol mixtures to provide water activities (aw) from 0.6-0.99. The water activity range includes the approximate water activity of the current final isolation step of the mirdametinib manufacturing process. Saturated suspensions were prepared by stirring an excess of mirdametinib in the test solvents for 16 hours. The suspensions were filtered and transferred onto mixtures containing equivalent amounts of Form VI and Form XIX.

The suspensions were stirred at the target temperatures, sampled at three and five days and analyzed by PXRD. The results are summarized below and show that all experiments produced Form IV. The hydrates may be kinetically favored at higher water activities.

Example 10: Drying of Certain Forms Via Vacuum Oven

Drying studies for certain forms were conducted overnight in a vacuum oven at 45° C. After drying, samples were equilibrated to RT for 10 min. and analyzed by PXRD at about 70% ambient lab humidity. The results are summarized below.

-   -   Form V (Toluene Solvate): Remained unchanged.     -   Form VI (Hydrate): Partially converted to Form A.     -   Form XIII (Hydrate): Form XIII/Form IV mixture converted to Form         IV.     -   Form XIX (Hydrate): Remained unchanged.

Desolvation/dehydration studies of certain forms were conducted in a TGA pan with loose lid at a heating rate of 15° C./min from 25 to 100° C. with a 5 min. hold at 100° C. Samples were air-cooled to RT on the TGA and analyzed by PXRD if crystalline. The results are summarized below.

-   -   Form V (Toluene Solvate): After cooling, observed sample to be         molten and transparent dark amber in appearance (melted and         solidified in molten, amorphous state, possible decomposition).     -   Form VI (Hydrate): After cooling, observed sample to be molten         and transparent dark amber in appearance (melted and solidified         in molten, amorphous state, possible decomposition).     -   Form XIX (Hydrate): After cooling, observed sample to be very         slightly sticky, but solid particles (not melted). PXRD         indicated Form I.

Example 11: Toluene-Spiked Slurry Studies

The process-relevant toluene solvate (Form V) was stirred in water:ethanol (1.1/0.5 v/v) overnight at RT with varying amounts of added toluene. The suspensions were filtered, and solids analyzed by PXRD. The results are summarized below.

-   -   With no added toluene, Form V converted to phase-pure Form IV.     -   With 0.5% added toluene (relative to mirdametinib weight), Form         V converted to mostly Form IV with some lesser amount of Form V.     -   With 1% and 2% added toluene, higher relative amounts of Form V         were observed, but difficult to distinguish between 1% and 2%         toluene, since PXRD data was qualitative and variable.

The results of the toluene-spiked slurry studies suggest that if crude mirdametinib from toluene/ethanol was the pure toluene solvate, controlling toluene levels going into the final crystallization would be critical. However, if the crude mirdametinib is mostly Form IV with lesser amounts of the toluene solvate, it may not be as critical to monitor toluene levels in the crude mirdametinib.

Example 12: Single Crystal X-Ray Diffraction Analysis of Form IV

A suitable single Form IV crystal was analyzed using a Bruker D8 Venture Photon II CPAD diffractometer equipped with a CuKα INCOATEC Imus micro-focus source (λ=1.54178 Å). The simulated PXRD pattern was calculated from the low temperature (100 K) structure and room temperature (298 K, 25° C.) unit cell parameters shown below. Unit cell at room temperature was initially determined by Difference Vectors method based on 235 reflections harvested from 151, 1° diffraction frames. Unit cell parameters were subsequently refined during data integration by Saint (Bruker (2020). SAINT. Data Reduction Software) and are based on 903 reflections recorded between 19.1 and 1.1 Å resolution. The simulated pattern was consistent with an experimental Form IV pattern as shown in FIG. 1A.
